Gems, Faceted Labmade Loose Gemstones","description":"\u003cp\u003eThese are faceted lab created rutile, titanium dioxide--each is individually photographed.  We have both near-colorless rutile (ranging from very faint yellow to light blue) and 'honey' rutile with a golden color--some of the honey rutile also has fine silky inclusions giving them a turbid or sleepy look.  These typically look milkier in the photos and more brilliant in the hand.\u003c\/p\u003e\n\u003cp\u003e\u003cbr data-mce-fragment=\"1\"\u003eThis is rutile, and it has the highest dispersion of any transparent gem material.  In practical terms that means it has the most insane fire you will ever see in a gemstone, throwing rainbows with the slightest provocation.  It is simply impossible to capture on camera--they look good in a picture but great in person.  It only has two downsides: its relatively low hardness around 6.5 (harder than tanzanite and suitable for pendant usage but not ideal for rings), and how difficult it is to get these days.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eCrystals of rutile are grown for a few high end optical applications, particularly for very powerful prisms, as well as for use as a substrate to grow other crystals on.  Production is fairly scarce today and often what we can get is of very low quality, so much of what we get is from old stock.  Some rutile is golden, some light yellow and it can very occasionally be a lighter blue or blue-yellow bicolor--all of them are absolutely stunning once cut.\u003c\/p\u003e\n\u003cp\u003eThis new honey rutile was actually grown specially for us--one of our partner growers used to produce smaller crystals of rutile and we convinced them to start back up and develop the process further, with us buying all the experimental crystals as they go.  The crystals require a great deal of trimming and annealing but they are getting better and

in the Dark GAGG Lumogarnet Facet Rough \"Long Glow\"!!","description":"\u003cp\u003eThese are lab-created GAGG (Gadolinium Aluminum Gallium Garnet) facet rough with pronounced phosphorescence (glow in the dark). Each piece is marked with its weight and you select which one to purchase.\u003c\/p\u003e\n\u003cp\u003eNote that, as a particularly defective crystal, some of these pieces will have a few bubbles.  The bubbles tend to correlate with the highest afterglow.\u003c\/p\u003e\n\u003cp\u003eThis is \"Long glow\" or \"high glow\" GAGG--a type of defective GAGG which exhibits a glow-in-the-dark effect.  They work pretty hard to avoid this happening since it makes the crystal useless for its intended purpose (detecting invisible radiation).  However mistakes happen and sometimes a crystal does show this effect.  Each one is a little different because the causes can vary, but this crystal shows a bright but short-lived initial glow which fades to a dimmer but long-lasting glow.  It was visible after at least an hour of sitting on my bedside table in the dark.\u003cbr\u003e\u003cbr\u003eCerium GAGG is brand new as far as gems go--it only entered industrial usage in 2014, and we just introduced it to the gem market last year. It is what we call a 'lumogarnet' - an exotic lab-created garnet with incredible fluorescence. We also call this 'Firefly Garnet'.\u003c\/p\u003e\n\u003cp\u003eLike Ce:YAG and LuAG GAGG is used as a scintillator, a crystal grown for its insanely strong fluorescence.  It is used to help detect invisible radiation by absorbing it and converting it to easily-detected visible light--gamma rays and x-rays will activate its glow in addition to UV and even normal blue light.\u003c\/p\u003e\n\u003cp\u003eProperties-wise this material is like an upgraded version of the classic GGG crossed with an aluminum garnet (like YAG and LuAG) to give it excellent hardness (8) while maintaining a high RI (1.9) and generally excellent gem properties. This material has very bright fluorescence, and like Ce:YAG and LuAG it is used as a scintillator to help detect invisible radiation.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"1pc

strong enough to give them a full color change to light blue in direct sunlight.  Some also have a mild afterglow, showing a blue glow after exposure to UV which can be seen in cupped hands.

It glows incredibly bright under UV light as well as higher energy radiation, and because of this it can be used to detect invisible gamma rays, xrays and even alpha rays. This type of LYSO has been optimized for ultra strong fluorescence with no afterglow (it does not glow in the dark, only with UV exposure). Its fluorescence is so strong it has a striking blue glow in sunlight--this effectively gives it a color change effect, since it looks colorless under room lighting and light purple-blue outdoors. It has a very interesting and unique look which you can't find anywhere else.\u003cbr\u003e\u003cbr\u003eAsianometry on youtube recently made a cool video about this material which you can watch here

that have to be withstood an ultra hard, ultra durable material like sapphire is needed.  But how do you make giant, flat sheets of sapphire?  Normally you'd cut windows out of a big round boule grown

ultra high tech crystal growing machine that grows the world's largest flat sapphires via the \"boat\" method aka HDSM.  If you've ever been to a Quiznos think of the ovens with a conveyer belt they use to toast subs evenly--it's basically that but with a giant flat pan of molten, crystallizing sapphire.\u003c\/p\u003e\n\u003cp\u003eThough the LANCE is absolutely incredible (we got to see it in person and meet the head crystal grower!!) it didn't have a 100% success rate, and over time the company built up a pile of defective sapphire crystals that had either been contaminated with titanium (which turns them pink and ruins UV transmission), developed bubbles, shattered during growth or usually all three.  They recently closed their factory in Chicago and auctioned off the contents, and

degree view in a wide spectral range.  With the incredible accelerations and speed that have to be withstood an ultra hard, ultra durable material like sapphire is needed.  But how do you make giant,

usually all three.  They recently closed their factory in Chicago and auctioned off the contents, and we were able to buy the entire pile of defective crystals!  It was a dream come

The way this is done is by cutting the garnet into square 'pixels', each of which is put in front of a sensor. When a gamma ray or x-ray hits one of the pixels they fluoresce and the sensor can detect the light, much like in a digital camera.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThese stones don't just glow, they reach out and grab the eye when exposed to sunlight, diffuse skylight and even indoor lighting.

fluorescence (hence why the pheonomenon was named after the mineral).  Specimens from the Blue John mine are known to change colors in sunlight because of their strong blue fluorescence, and this phenomenon attracted the interest of scientists.  Crystals with a strong glow are valuable because they can be used as 'scintillators' for detecting the presence of invisible radiation, and it turned out if they grew fluorite with the element europium in it they could produce this very strong blue glow.  Eu:Fluorite's glow is strong enough to change its color in direct

garnets will glow in the dark after exposure to bright light, even normal white LEDs like a phone flashlight (though blue or UV will charge them better).  The glow is quite bright at first, then fades

scientific and medical equipment.  It's new as a material, only commercially available for technical applications in 2014, and very new as a gem since we first brought it to the gem market in 2022.  It is what we call a 'lumogarnet' - a lab created garnet with incredible fluorescence--and, rarely, phosphorescence! The ones with great phosphorescence we also call 'Firefly Garnet'.\u003c\/p\u003e\n\u003cp\u003eThat's right, these particular examples glow in the dark!  They actually do their best to prevent that from happening because it makes them less effective for technical use, but every now and then growth goes wrong and a crystal will have some afterglow, and an even smaller percentage are also clean enough to facet into gems.\u003c\/p\u003e\n\u003cp\u003eGAGG is a durable gem with a high hardness of 8 and no cleavage.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"Pendant with Round

can be more easily detected, and cerium YAG was the first of the garnet scintillators, though it has since been mostly replaced with denser GAGG and LuAG.  It isn't as bright as GAGG or LuAG but it
